Merge branch 'es/format-patch-rangediff'
"git format-patch" learned a new "--range-diff" option to explain the difference between this version and the previous attempt in the cover letter (or after the tree-dashes as a comment). * es/format-patch-rangediff: format-patch: allow --range-diff to apply to a lone-patch format-patch: add --creation-factor tweak for --range-diff format-patch: teach --range-diff to respect -v/--reroll-count format-patch: extend --range-diff to accept revision range format-patch: add --range-diff option to embed diff in cover letter range-diff: relieve callers of low-level configuration burden range-diff: publish default creation factor range-diff: respect diff_option.file rather than assuming 'stdout'

--cover-letter --interdiff=feature/v1 -3 feature/v2`).

--range-diff=<previous>::
|
||||
As a reviewer aid, insert a range-diff (see linkgit:git-range-diff[1])
|
||||
into the cover letter, or as commentary of the lone patch of a
|
||||
1-patch series, showing the differences between the previous
|
||||
version of the patch series and the series currently being formatted.
|
||||
`previous` can be a single revision naming the tip of the previous
|
||||
series if it shares a common base with the series being formatted (for
|
||||
example `git format-patch --cover-letter --range-diff=feature/v1 -3
|
||||
feature/v2`), or a revision range if the two versions of the series are
|
||||
disjoint (for example `git format-patch --cover-letter
|
||||
--range-diff=feature/v1~3..feature/v1 -3 feature/v2`).
|
||||
|
||||
--creation-factor=<percent>::
|
||||
Used with `--range-diff`, tweak the heuristic which matches up commits
|
||||
between the previous and current series of patches by adjusting the
|
||||
creation/deletion cost fudge factor. See linkgit:git-range-diff[1])

for details.
